R.java is missing implicate that your resource folder is having some issues. please try to look at your resource files(layout,drawable etc). and after that clean the project. it will solve the problem for sure.

Then android target is not set. project->right click->Properties->android and set the android target

If the android Target is not set .The library classes like Activity ,won't import.Anyhow,I've set my project to API 17
Have you checked that your builders are set up correct? To have the R.java file generated there's a need that the Android Pre-Compiler has processed all the resources.
In Eclipse go to "Project --> Properties" and select "Builders" from the list.
Only if these builders are set, the R file can be generated.

Your answer in my case is not effective on my project. Once I created a project, I noticed that there is no R file in the gen folder. What should I do?

@DavidDimalanta Have you already created a build? "Project => Build all" (maybe you have to uncheck "Build automatically") - are there any errors you get? If you don't succeed, please ask a new question.

I have selected all the builders and clicked ok. I cleaned and build project again but still R.java is not generated.

Hi @M.S. - would you mind opening a new question if all these answers didn't help you out?
R.java missed only when there is some problem in resource files. Check properly your Menu files , layouts, and Drwables, (sometime same image names with .jpg and .png extensions are existeing).
Or you can create new project and paste everything in new project then check it again.

I can't see my logcat as I can't even run my project with this error .if I run my project a dialog shows that my project contains error(s),please fix them before running my application

if you are using any menu xml please remove it for a while and test your project without using menu xml. then clean your project and test it. because some time there is some problem in menu file and eclipse dont indicate with red cross.
- click Project --> Build Automatically
- check build automatically
- clean the project

I have face this problem many time but everytime due to this problem only ,you can try restarting eclipse , mean while i ll try what else can i find for you
simple way! go to import section (top of current java class) and remove wrong import R, then go over the R and click Alt+Enter, then android studio import true R.
